Skin Error after UpgradeCancel

I applied the patch for SP2 today and they project compiles fine. When I try to edit a page however I get the following error:

Telerik.Web.UI.RadPanelBar with ID='RadPanelbar1' was unable to find embedded skin with name 'Default2006'. Please, make sure that you spelled the skin name correctly, or if you want to use a custom skin, set EnableEmbeddedSkins=false.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.InvalidOperationException: Telerik.Web.UI.RadPanelBar with ID='RadPanelbar1' was unable to find embedded skin with name 'Default2006'. Please, make sure that you spelled the skin name correctly, or if you want to use a custom skin, set EnableEmbeddedSkins=false.

Source Error:

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

The "Default2006" skin is
no longer used. It has been removed from Q1 RadControls for ASP.NET AJAX
distribution which we use. Instead Default2006 you can use "Default"
skin. Find the control with the ID="RadPanelBar1" and change the skin
property in the control declaration. You can gather more information from the following discussion at http://www.telerik.com/community/
